Many thanks for that extensive reply.. The choke idea is interesting and something to be seriously considered (if no radials 5/8 has to be the choice). I can see there are some real performance drawbacks here with the "danglies" then which may mean there is no advantage, depending on what the definition of a portable, fast and high performance antenna ends up being..
I am going to have to do this.. can I see a model of a T2LT ? and not the dipole many speak of and present when speaking about this antenna.
A coaxial antenna, because I have never seen one modeled and I have had poor experiences with T2LT with DX (with the choke of the T2LT about 5-7m high) and I have some suspicion that something is awry with its radiation pattern. (despite often drawing parallel to a "half wave dipole")
For some reason I have done better with a 1/2 wave end fed silver rod type antenna and would choose one every time over a T2LT.. (other than when you cannot be bothered with anything better)
Your thoughts appreciated... could there be something odd about the radiation pattern from T2LT give its unique design. It is clever I will give it that.
Just a few thoughts on it... could the coaxial coil be extra lossy? Could the way the antenna is set up somehow mean it would not have a radiation patter like a dipole ? Could for example that coaxial choke make an antenna tune but in reality there are some CMC's under the choke which messes the pattern up (unlike a true dipole).. i.e. if there was 1/8 wave of CMC breaking through and under that choke could that mess its pattern up ? (1/8 wave just being a random example)
I mean.... I don't know but I have found the antenna had lackluster performance when I have used it myself. I am sure in good conditions it will work DX.. but when there are poor conditions (weak ionization) ... when antennas tend to show their real value I found it lacking.
